SBC Waste Stream Classification Various Locations Paste 2 of 2 California minutes, after which water was collected into eight (8) labeled 40 -ml VOAs for analysis. This procedure was followed at each of the four sites. Four (4) of the VOAs from each site were stored in a cooler with ice and delivered to Sun Star Laboratories located in Tustin, CA to be analyzed for EPA Method 8015cc (carbon chain). The four (4) remaining VOAs were delivered to MBC Applied Environmental Sciences located in Costa Mesa, CA to be analyzed using a DOHS Title 22 Fish Bio Assay. /i:T[Naf gTgJ*1I1� ' The samples collected were analyzed for total extractable hydrocarbons using EPA Method 8015cc (carbon chain) and for a 96 -hour aquatic test using DOHS Title 22 Fish Bio Assay. The California Code of Regulations (CCR), Title 22, Section 66261.24 states that if a waste, (1) contains any of the substances listed in section 66261.24(ax7) (including extractable petroleum hydrocarbons) at a single or combined concentration equal to or greater than 0.1 percent by weight, and/or (2) does not pass the 96 -hour Fish Bio Assay testing with greater than 50% survival at the 500 mg/L, it can be classified as hazardous. If a waste contains extractable hydrocarbons at a concentration greater than 0.1 percent by weight, but passes the subsequent 96 -hour aquatic bio assay testing with greater than 50% survival at the 500 mg/L, and 60% survival at 750 mg/L, it is declassified as hazardous waste. Analytical results for the spill bucket sampling reported that one (1) of the eight samples analyzed was found to contain total extractable petroleum hydrocarbons at a concentration of 1100.15 mg/L, which would be classified as hazardous waste according to the CCR Title 22 regulations. However, results from the aquatic bio-assay testing report 100 percent survival at both 500 mg/L and 750 mg/L, which permits the waste to be classified as non -hazardous. The remaining seven (7) samples collected met both CCR Title 22 requirements for non -hazardous waste classification. The analytical results are summarized in ,1 Table 4. CONCLUSIONS Based on the random study performed throughout the state of California, all water samples analyzed in the spill buckets at SBC sites were deemed non -hazardous. The study shows that detectable concentrations of diesel were absorbed in the water Intrusion. Regardless of the level of concentrations, all samples passed the aquatic bio-assay testing report 100 percent survival at both 500 mg/L and 750 mg/L, which permits the waste to be classified as non -hazardous. This study can support a self -declaration for future classification of water Intrusion waste stream as non- hazardous for the purpose of manifesting and final disposition.
